Virus Scanner FAQ

What is a computer virus?
A computer virus is a type of malicious software that attaches itself to legitimate programs or files and replicates when executed. Viruses can corrupt data, steal information, log keystrokes, and even render your computer unusable.
How does a Virus Scanner work?
A virus scanner examines files on your computer, comparing them against a database of known virus signatures. Advanced scanners like Loaris also use heuristic analysis to detect new, unknown threats based on suspicious behavior patterns.
Is a free Virus Scanner enough?
A free virus scanner is great for on-demand scanning and removing existing infections. However, for continuous protection and real-time threat blocking, upgrading to Loaris Trojan Remover provides comprehensive security.
How often should I scan for viruses?
We recommend running a full system scan at least once a week. If you frequently download files or visit unfamiliar websites, consider scanning more often. Regular scans help catch threats before they cause damage.
